18QHTF21-1.600-PD

Overview

The 18QHTF21-1.600-PD is a crystal oscillator manufactured by Mercury Electronic Ind. Co., Ltd. It operates at a frequency of 1.6 MHz and utilizes LVCMOS output logic. The device supports a supply voltage of 1.8V and includes a power-down feature for standby mode. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6 mm.

Feature Summary

• Integrates LVCMOS output logic for standard digital interface compatibility
• Supports power-down functionality to enable low-power standby operation
• Utilizes a leadless SMD package design for surface-mount assembly

Applications

• General clock signal generation in electronic circuits
• Timing reference sources for embedded systems
• Consumer electronics requiring precise frequency control

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct configuration. Confirm that the required supply voltage and output logic levels match the target system requirements before procurement. Ensure the package type aligns with the available footprint on the printed circuit board.

Selection Notes

Select this component when a 1.6 MHz timing source is required with LVCMOS outputs. Consider the 1.8V operating voltage and the availability of a power-down pin for energy management. Evaluate the 2.0x1.6 mm package size against spatial constraints within the final assembly design.

Part Context

This part belongs to the 18QHTF21 series of oscillators from Mercury Electronics. The series typically offers various frequencies and voltage options. The -PD suffix indicates the inclusion of a power-down control feature, distinguishing it from standard continuous-operation variants within the same family.

Replacement Considerations

Consult official substitution lists for compatible alternatives. Verify that any replacement matches the 1.6 MHz frequency, LVCMOS output, and 1.8V supply voltage specifications.
